Sakura
To Sakura's surprise and shock, the girl responded to the man by pushing him hard into the ground, leaving a small crater where his head impacted. Momentarily worried that she might have casually killed the man, Sakura considered backing-off and calling for help, but, to her relief, the man spoke, clearly hurt by the fall but seemingly undamaged.
Once more, Sakura did her best to hide her emotions, only perhaps a slight hint of surprise and shock showing through. However, she could see that she needed to be very careful around this girl. If Sakura upset her like this man had, she could easily get killed by the reaction, perhaps without the girl even intending it.
